PHCA Community Meeting | Recognizing Passive House Performance within California Title 24

This presentation will explore how Passive House (PH) residential projects perform relative to California’s 2025 Title 24 Energy Code by comparing the Passive House Planning Package (PHPP), WUFI Passive, and California’s CBECC compliance software across all 16 California climate zones for illustrative single-family and multi-family prototypes. It encompasses a structured comparison of how the same Passive House-related design strategies are represented across modeling platforms, where assumptions can be aligned, and…


PHCA Community Meeting | Complexities in Selecting Passive House Windows

The California energy code has very simple requirements that windows have to meet in order for a project to comply with the energy code. Certified Passive House buildings, on the other hand, have a much more nuanced approach to analyzing and specifying windows. This can present some difficulties for designers, architects, energy modelers, and builders. This presentation aims to demystify these requirements and provide clear guidance as to the best…

AB 368 made it thorough Appropriations

AB368 (Passive House Bill) passed through the appropriations committee. The goal is to consider adopting the International Passive House Construction Standard standards, as an alternative compliance pathway within California's Building Energy Efficiency Standards (Title 24). This initiative aims to promote the construction of high-performance, energy-efficient buildings that contribute to the state's climate goals. Passing the Appropriations Committee indicates that the bill has been reviewed for its fiscal impact and deemed viable…


Implementing Passive House in Title 24 | California Bill Proposal

Climate Action California Needs Your Help - Together, we can make a difference! Passive House California (PHCA) is backing the Climate Action California proposal to integrate the global Passive House construction standard into California’s Energy Building Code Title 24. This move would allow the Passive House Standard to be incorporated into the code as an alternative compliance pathway, enabling the establishment of an ambitious, climate-conscious reach code. This approach represents…
